Abstract

The utility model discloses an illuminator. A spotlight cup is arranged on a lamp holder. A single-particle LED light source chip which is connected with the lamp holder is positioned in the spotlight cup. A heat dissipation case is held on the exterior of the spotlight cup. The lamp holder is arranged on a plastic body which is connected with the heat dissipation case. A glass lens is positioned on the spotlight cup, which is clamped in the inner ring wall of the heat dissipation case. The inner side of the spotlight cup on the heat dissipation case which is fixed through a glass tightening coil is also provided with an electromagnetic ripple. The illuminator adopts the heat dissipation case which is larger than the spotlight cup for dissipating heat effectively. The inner side of the spotlight cup adopts the electromagnetic ripple surface, which can prevent glare effectively and ensures the illumination light uniform. The glass lens can prevent dust from entering into the lamp and keep the illuminator clean. The LED light source chip is long in life and saves electric power under the same brightness and the electric power consumption is only 20% as common bulbs.

Description

A kind of illuminating lamp

Technical field

The utility model relates to technical field of lamps, is meant a kind of illuminating lamp especially.

Background technology

In the middle of daily life, illuminating lamp is widely used, and of a great variety.Wherein the structure that a kind of illuminating lamp adopted is to use the high power light source of many 1W, and many light sources are welded on realization illumination on the aluminium base.This illuminating lamp is owing to add lens on many light sources, the hot spot effect that causes producing has a very little brighter hot spot of scope for middle, and very dark on every side, brightness irregularities can not reach the requirement of illumination; And because illuminating lamp has aluminium base, increased thermal resistance, made the heat of light source not derive rapidly, caused temperature higher, shortened the service life of light source and caused bigger light decay.

The utility model content

In view of this, the utility model is to provide a kind of illuminating lamp, and is inhomogeneous to solve above-mentioned lighting brightness, the heat problem of higher.

For addressing the above problem, the utility model provides a kind of illuminating lamp, comprising: be installed in the prefocus cup on the lamp holder, the single LEDs light source chip that connects lamp holder is arranged in the prefocus cup, the outside of prefocus cup has held heat-dissipating casing.

Wherein, lamp holder is installed on the plastic body, and plastic body connects heat-dissipating casing.

Wherein, the screw that is connected between plastic body and the heat-dissipating casing is connected or is threaded.

Wherein, have glass lens on the prefocus cup, glass lens is held in the inner ring wall of heat-dissipating casing, and is fixed on the heat-dissipating casing by the glass tight loop.

Wherein, the glass tight loop is fixed on the heat-dissipating casing by screw or screw thread.

Wherein, the inboard of prefocus cup also has the electromagnetism line.

Illuminating lamp adopts the heat-dissipating casing greater than the optically focused cup, can effectively dispel the heat; Light source chip adopts single chips, can reduce heat radiation; Electromagnetism line surface is adopted in the inboard of prefocus cup, can effectively prevent dazzle, guarantees that illuminating ray is even; Glass lens can prevent to enter in the lamp dust, keeps the illuminating lamp cleaning.

Description of drawings

Fig. 1 is the structure chart of illuminating lamp among the embodiment;

Fig. 2 is the cutaway view of illuminating lamp among the embodiment.

The specific embodiment

For clearly demonstrating illuminating lamp of the present utility model, provide embodiment below and be described with reference to the accompanying drawings.Referring to Fig. 1, Fig. 1 is the structure chart of embodiment, and among this embodiment, illuminating lamp comprises: the prefocus cup 3 on the lamp holder 7 is installed, the single LEDs light source chip 4 that connects lamp holder 7 is arranged in the prefocus cup 3.

Lamp holder 7 also can be installed on the plastic body 6, and connects prefocus cup 7 by plastic body 6;

On plastic body 6, also heat-dissipating casing 5 can be installed, during installation, can or be threaded by the screw connection, and prefocus cup 3 is held in the heat-dissipating casing 5; The shell sizes of heat-dissipating casing 5 is because greater than the shell sizes of prefocus cup 3, therefore, can be effectively will single the heat that produces of led light source chip 4 distribute, the interior temperature of the lamp of avoiding heat in the lamp to distribute not going out and cause is too high, influences circuit working.

The inner ring of heat-dissipating casing 5 also can hold glass lens 2, and after holding by glass tight loop 1, is installed on the heat-dissipating casing 5 with screw, or by being threaded on the heat-dissipating casing 5.Glass lens 2 can prevent that dust from entering in the lamp body.

Lamp holder can adopt the standard lamp of E27 first-class, and the inner surface of prefocus cup also can have the electromagnetism line, produces dazzle to reduce light source chip when luminous, makes illuminating ray even.

Illuminating lamp in the utility model, thermal diffusivity is good, and light illumination is evenly sufficient, and the prefocus cup that adopts the electromagnetism line to handle can effectively prevent dazzle.Light source adopts state-of-the-art in the world at present semiconductor solid luminescence body, single LEDs light source chip, and power reaches 15W, be present domestic maximum, the life-span can reach 50,000 hours, is 10 times really of common bulbs, and under same brightness, power consumption only is 20% of a common bulb.

For the illuminating lamp of being set forth among each embodiment of the utility model, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
